SPECIFICATION forming part of Letters Patent No. 744,166, dated November 17, 1903.

Application filed July 15, 1903. Serial No. 165,559. (No model.)

To all whom it may concern:

Be it known that I, MERTON CHURCH, a citizen of the United States, residing at Detroit,

county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Wire-Fence-Staplin g Devices, of which the following is a specification, reference being had to the accompanying drawings, which form a part of this specification.

My invention is designed to provide certain new and useful improvements in a wire-fence machine, the samebeing more particularly designed to provide an improved wire-fencest-apling device for joining fence-wires or for applying suitable staples to join the upright and horizontal wires of the fence in a superior and efficient manner.

I carry out myinvention as hereinafter described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a View in end elevation illustrating features of my invention, showing parts broken away. Fig. 2 is a view of certain features embodied in Fig. 1 in vertical section. Fig. 3 is a View in front elevation, showing the swinging beam. Fig. 4 is a view showing the horizontal wire and the vertical wire secured together by a staple, the vertical wire being in section. Fig. 5 is a view of the same, showing the upright wire, the horizontal wire, and the staple, the horizontal wire being in section, Figs. 4 and 5 showing the work accomplished by means of my invention.

A wire-fence machine of which my present invention constitutes a feature, itwill be understood, is designed to construct a wire fence consisting of a series of horizontal wires a, united to a series of upright wires b, the horizontal and upright wires being.

united and held together at the point of their intersection by means of a two-pronged staple c, the prongs of the staple being clenched over and about the upright wires, the loop of the staple embracing the horizontal wires, the upright and horizontal wires being thereby held firmly in engagement the one with the other.

My present invention has the same object in view as that embodied in the United States Letters Patent granted to me April 24, 1900, No. 648,239, the means, however, of accomplishing the object difiering in certain material respects from the means shown and described in said patent. As stated in my said patent, in joining the upright and horizontal wires the upright wire is slightly indented, preferably at the point of the intersection of the horizontal wire, as indicated at d.

In the mechanismembodied in my present invention I employ a suitable casef,constructed with an orifice therethrough, as at g, to receive the horizontal wire and with an additional orifice, as at h, to receive the vertical wire. The orifices g and h are arranged so that the horizontal and vertical wires will lie adjacent the one to the other. Said case is also formed with a suitable runway, as at 73, through which the staples may be fed. Leading from the inner end of the channel i is an additional channel, as at j, through which a single staple may descend to be engaged with the wires.

channel j to force the staples one by one into proper position to engage the wires. The staples, it will be understood, when forced firmly into place descend over or astride the horizontal Wire. To hold the two wires firmly in place while the operation of bending the prongs of the staple is in process, a plunger Z is forced into contact with said Wires, as indicated more particularly in Figs. 1 and 2. To bend the prongs of the staple as required to accomplish the work designed by .my invention, I employ a swinging clenchingarm m.

It will be understood that there are employed in my invention a series of the cases f, with their plungers 7c and Z, a corresponding series of clenching-arms m being also employed for bending the staples about the intersecting point of the upright and horizontal wires. The swinging'arms m may be oscillated in any suitable manner and by any suitable mechanism. As shown in the accompanying drawings, such a series of arms m may be secured to an oscillatory beam '21, having its bearings upon shafts of the machine, (indicated at p p.) Said arms may be secured to the swinging beam also in any suitable manner. As indicated in the drawings, the beam is constructed with aT-shaped slot p to receive the heads of bolts 7, said bolts A plunger 10 is madereciprocatory in any suitable manner in the too united by a clip 3 over the adjacent portion of the arm, nuts ibinding the boltszin place.

' One of the bearings upon the adjacent shaft q is provided with a segmental gear 'v, with which meshes a reciprocatory rack-bar u, reciprocated from any suitable portion of the wire-fence machine. It will be evident that by the reciprocation of the rack-bar u the beam 71, with its arms m, will be oscillated, the center of oscillation being coincident with the point of intersection of the upright and horizontal wires. I prefer in the initial operation of bending the points of the staple that they should be driven down against the end face of the arm 071, preferably an oblique face, by the plunger 70, the points of the staples by this operation being given a partial bend, as'indicated in full lines in Fig. 2, this partial bending of the prongs by the action of the plunger 70 against the end face of the arm at being accomplished while the arm m is stationary or before said arm has begun its oscillatory movement. This partial bending of the prongs in this manner limits the required oscillation of said arms, inasmuch as said arms need only to oscillate or swing a suflicient distance to further bend the prongs into proper position, as indicated by the dotted position of the arm and of the prongs in Fig. 2. Thus I accomplish by means of the one set of swinging arms m, together with the plungers It, the entire bending of the prongs of the staple. I do not limit myself to any particular mechanism for reciprocating the plungers or for feedingthe staples to the machine. The case f may be of any suitable construction to serve for a plunger-guide and to form a guide for the upright and horizontal wires.

It is evident that the swinging arms 072 may be adjusted laterally upon the beam as may be desired.

The operation of the mechanism embodying my invention will now be understood.

The loop of the staple is preferably made to offset or set forward overor in a plane with the upright wire, as indicated in Fig. 4 at c. This is accomplished by arranging the plunger k at an acute or oblique angle, as shown.

What I claim as my invention is- 1. In a wire-fence machine, means to carry horizontal and vertical intersecting wires, mechanism to feed the staples to the intersection of said wires, and an oscillatory device to bend and clench the prongs of the staple over one of said wires.

2. In a wire-fence machine, means to carry horizontal and vertical intersecting wires, mechanism to feed the staples to the intersection of said wires, and an oscillatory device to bend and clench the prongs of the staple over one of said wires, said plunger constructed to force the prongs of the staple against said device while the device is stationary and thereby partially bend the prongs of the staple.

3. In a wire-fence machine, means to carry horizontal and vertical intersecting wires, mechanism to feed the staples to the intersection of said wires, and an oscillatory device to bend and clench the prongs of the staple over one of said wires, said oscillatory device being laterally adjustable.

4. In a wire-fence machine, means to carry horizontal and vertical intersecting wires, mechanism to feed the staples to the intersection of said wires, an oscillatory device to bend and clench the prongs of the staple, and an oscillatory beam carrying said device.

5. In a wire-fence machine, means to carry horizontal and vertical intersecting wires, mechanism to feed the staples to the intersection of said wires, an oscillatory device to bend and clench the prongs of the staple over one of said wires, a segmen tal gear to oscillate said device, and a reciprocatory rack-bar to actuate said gear.

6. In a wire-fence machine, a case provided with horizontal and vertical intersecting wirereceiving channels and with a suitable feeding-channel, said case having in combination therewith a reciprocatory plunger to force the staples into place, and an oscillatory device to bend and clench the prongs of the staple.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

MERTON CHURCH.
